ROPE AND CHAIN

CHAINWHEEL SELECTION GUIDE
In order for your windlass to retrieve and deploy the anchor and chain smoothly, without jamming, it is vitally important that the chain and chainwheel (gypsy) match.

Unfortunately all chains (whether metric or imperial) are not necessarily manufactured to the same tolerances for a given chain size. Therefore, Maxwell has devised a global chain and chainwheel spreadsheet which will help you to figure out what chainwheel you need to order, for the chain you are using, to fit and work correctly with your Maxwell windlass.

If you know the chain size and manufacturer, then simply go to the Maxwell web site, look up your chain, scroll down to your windlass and a dot in the matrix will indicate and guide you to the chainwheel to be used with your specific windlass and chain. If you do not know the chain size and manufacturer, then use the illustrated chain diagram (below) and indicated dimensions information to ‘measure’ your chain. Send this information to your Maxwell dealer, who will then help you figure out what chain you are using and therefore what chainwheel must be used with your Maxwell windlass.

CHAIN INFORMATION
There are various Grades of short link chain. The Grade relates to the raw metal quality, strength and finishing process. Both galvanised and stainless steel chains are available.
Chain Specification is the Standard a chain must be manufactured to in order to comply with a given International Standard.

Outside of North America the most common types of metric short link chain are DIN766 and EN-818. Within North America the most common imperial chains are BBB and G40.

The important thing to keep in mind is to select a chain grade and specification that complies with recognised standards.

In addition to the chains listed above, Maxwell can supply a variety of alternatives to meet any market demand. Contact your nearest Maxwell Dealer.

ROPE AND CHAIN

Maxwell can supply a full range of anchor rodes including chain only, rope only or pre-spliced combination rope and chain rodes. Chain, suitable for vessels up to 100 metres (about 300 feet), is available in short or stud link variations in both metric and imperial sizes. Maxwell stocks both 3-strand and 8 plait (braid) nylon rope commonly used on vessels up to 20 metres (65 feet) as well as ropes and hawsers commonly seen on superyachts.

CHAIN SNUBBERS

Chain snubbers are an alternative method of taking the load off the windlass and are recommended to secure the anchor while underway. Available in rope versions with chain clevis hook (A) or snap shackle (B) and in various sizes: 6mm (1/4"), 8mm (5/16"), 10mm( 3/8"), 13mm (1/2").

MAXWELL ANCHOR TENSIONER

The innovative Maxwell Anchor Tensioner is designed to meet the market demand for a simple, easy to
use and adjustable anchor tensioner which secures the anchor firmly into the bow roller, taking the weight off the windlass and preventing accidental deployment of the anchor while under way. Secured to an existing cleat or bollard, there is no installation required. Simply loop the bitter end of the high strength webbing, which has 5oomm (18") of adjustability, over a cleat or bollard, engage the tensioner 'claw' on the chain, and lock the cam-action lever which can be further secured with a quick release pin (supplied).

Suitable for use with 7mm (1/4") to 12mm (1/2") short link chain

Not to be used as a snubber while laying at anchor

Do not use the windlass capstan to secure bitter (looped) end of webbing.
